Works as advertised. My mistake was putting them on a mask that I ultimately decided against using. Great to me able to see my watch and gauges. Probably would have done one eye at a time in case I changed masks.

the portion of the lens with the correction is not TALL enough (top to bottom height). if just a little bit of water gets in the mask it covers up the corrected portion. the corrected portion needs to be at least twice as tall as these are.

I found the close up portion of the lenses to be too small and too low in my field of vision. Next time I will splurge and get the full lenses.

After fighting it for years, I finally came to the conclusion that my near vision was making it very difficult to see my computer and camera controls underwater. These lenses restored sharp vision. If you dont know what diopter you need, go down to the local retail pharmacy and try on the various reading glasses that come in set diopters. I determined that I needed +2.0, and this was exactly right when the mask came. My only suggestion is that you only need one lens on one side (dominant eye) as it is very difficult to actually look through both right and left lenses at the same time at something close. I mainly just looked through the left lens.

i would caution people not to expect too much or to be aware that above and underwater needs can vary. i use +2.5 reading lenses on the surface and hoped the +2.5 s would help in reading gauges and wrist computer. they dont really, and the line resulting from the ion doesnt help either. i will probably put the original lenses (which they send to you) back in.

Tusa Liberator bifocal lens
Reviewer:
Laura A Kilty
It is nice to be able to order a lens for us older scuba divers so that we can easily see our gauges and camera settings. The liberator stock lenses were nice to order online however I found after trying them out in the pool with my underwater camera that they were not constructed correctly. With the liberator mask on my face and swimming in the scuba position I am usually looking through the top of my masks lens. Unfortunately the stock bifocal lens is set too low in the mask to be useful. The bifocal needs to be higher by at least 1 cm and the optical center of the bifocal lens needs to be closer to the inner aspect of the lens to account for the near interpupillary distance. Opticians, optometrists, or ophthalmologists need to be consulted to construct these lenses so they are more functional. I am an eye doctor so I know what would work better optically.

Works great. However, get just one. You cant use both bifocals at the same time, and one is plenty for checking gauges. Alternatively I would consider getting one full lens with the distance Rx and one with a near Rx. It is hard to see small things with the near correction positioned low, like a bifocal.

Oh, with bifocals you can see what your computer says. You are able to read what your computer is telling you but the bifocals need to be larger because it is very hard
to find what you are what you are trying to see-it has to be in an exact position.

the odyssey bifocal lens replaces the standard optical glass lens in a two-window dive mask. if you have good distance vision but need reading glasses, this is an excellent, durable solution. i have tried the glue-in magnifiers but they never last more than a few dozen dives my last set of odyssey optical glass bifocals lasted over 1500 dives!

Lens works well but I would prefer it to be another 1/4 inch taller. I find I have to consciously look way down, to look through the bi-focal section in order to read my gauges.

The 2x optical works fine, good choice! Much better than the "stick on" version that washes out when you rinse the mask!

On first try I feel for the diver who is using these lens for more than gauge viewing will find the reading portion too small should be higher.
